@cchurch5 Quoting from their website: "Our testing showed that Spark successfully supports weights of over 100lbs on the upper level!" It looks like Spark will support monitors on the upper level - which Oristand cautions against.

@cchurch5 The biggest difference is that we opted for very stiff and robust over folds flat in a jiffy. Spark also provides a slight negative tilt on the keyboard tray, in keeping with the most current ergonomics: http://www.quittingsitting.com/d... .

@cchurch5 One more thing - Spark's keyboard tray is offset horizontally (flippable for lefties), to provide plenty of room for your mouse / trackpad, but still keep your keyboard lined up with your screen.

@joshpuetz Hey Josh, as Fatima mentioned above, our testing showed that Spark supports over 100lbs on the upper level. But more important to most people than strength is stiffness - Spark doesn't wobble at all while you type or mouse.

@maxwellhallel Hey Max, our beta testers indicated en masse that they much preferred a robust, lightweight solution that they could easily move in / out than a less robust folding option like some others. Spark is easy enough to disassemble / reassemble to be a great travel companion, but you likely won't want to break it down and build it up every day.
